MACHINE FOR WINDING ARMATURES FOR DYNAMIC-ELECTRIC MACHINES.

Specification of Letters Patent.

Patented July 11, 1916.

Application filed August 1,1914. Serial No. 854,528.

To allrohom it may concern Be it knownthat I, KoNuAo Rmocaa Rrr- TER, englneer, a subject of the Emperor of Austria-Hungary, residing at '4 Vostitz lVallwitzstrasse, Leipzig-Schiinefeld, Germany, have invented new and useful Improvements in Machines for Winding Armatures for Dynamo-Electric Machines, of which the following is a specification.

This invention relates to machines for winding armatures for dynamo-electric ma-v chines of the type in which holding means for the armature provided with guides for the wire to be wound thereon and a wire delivering device are arranged so as to rotate relatively to. each other about an axis at right angles or substantially at right angles to the armature shaft.

The invention consists in the special construction of the holding device for the armature and the wire delivery device, and in other detail improvements in the construction of the machine as hereinafterdescribed.

The invention will be described with ref erence to the accompanying drawings; in which one form of construction is illustrated. I

Figure 1 is a front view of thewmachine.

Fig. 2 is a diagrammatic plan view showing.

the relative positions of the armature and the holding cheeks. Fig. 3 is a front view of a holding cheek with a wire guiding device. Fig. 4 is a plan of same. Fig. 5 is a section through the holding cheek on line 5-5 of Fig. 3.

On two supports a, a. are mounted the bearing pedestals I), I) in which are jour-' naled the shafts c. c of two disks (Z, d. In each of these disks are fitted two holding cheeks c, c (Fig. 2) provided with extension pieces f (Figs. 8 and 4). Between these cheeks the armature 7 is gripped in such a manner that its axis h is at right angles to the shafts c, c. that it can, by means of a screw 2', a handwheel is and a spring suitably arranged, be moved a greater or lesser distance toward the armature g in order to grip the latter tightly between the cheeks c, e.

Upon the disks (Z, d are secured, in any suitable manner, holders Z, Z which serve for the support of her -like' shaped guide devices m or of wire h lders a. When the armature is wound so, that the windings pass on on]; one side of the shaft. the guide horns m are secured in the holders Z on one The shaft 0 is arranged so side, said guide horns m serving to hold the wire from engagement with the armature shaft. as more fully described below. The wire holder n may then be secured in the holder Z as also more fully described hereina fter,

On the holding cheeks e, e are adjustably secured the wire guides 0, 0 which serve to guide the wire directly into the armature groove to be wound. The wire is wound from a supply spool (not shown in the drawings) behind the supports a, a and passes through the opening p over the spring rollers or tension rollers q, 1 and then to one of the guide horns m and past the wire guides 0, 0 to the wire holder 1 to which it is secured by its end. The shafts c, c are then, by means of the pulley r or in any other suitable manner, caused to 1'0- tate continuously, so that the wire 8 s wound in the armature groove determined by the position of the wire guides 0, 0. It is to be observed that wire guides 0, 0 are also provided on the opposite side of the armature. to those shown, the bent out ends of which in the arrangement of the parts shown in Fig. 1 would extend downward, but, these are omitted from the drawing so as not to unnecessarily complicate it. The horns m, during winding, guide the wire as it passes from the supply spool away from the armature shaft h.

When a winding is finished the wire is again led to the wire holder n and cut off, then, by means of the foot lever t, through the medium of the shaft 11, the link i) and the bell-crank lever in, the check 6 may be withdrawn somewhat in order that the armature 9 may be turned around to present the next groove for winding, when the foot lever is released and check (2 again moves forward to grip the armature. To permit of being rotated in this way. the armature 'is carried upon a conical pointed foot-step m, which enters the end of the armature shaft and is mounted upon an arm 37 carriedby the support a.

The latter is secured to one ofthe cheeks e in-any suitable exceeding three. the wire, in order to simplifv'the operation, is not out after the completion of the first three windings, but only led over the hook n and then further wound.

This is ropeated until the coils to be around in the groove are completed. Then tho combined wirss are out directly in front hook a arid. ropresonts the beginning of tho coil, wliils the other. standing out, forma tho and of the coil. This lightens the Work of conneoting up the corresponding Wire ends Before cutting the Wires, the coils are sccurcd, ay Wooden Wedges or the like, in the two grooves of the armature. containing tliouu so that they cannot become loose, when the wires are cut.

The guide horns *m are mounted by means oi? pivots on the heads 3 of spindles 4i and by means Uftlgl'll) and left handed screws 5 in correspondingly double thrcaded nuts 6 are oivotally conneotsd to tho hands 3 so that by rotation ofilio nuts 6 they may loo inclined more orx loss with regard to the arnnituro a sit Their position can also no ronulaiod radially by means oi. the nuts 7 upon time spindles 4.

When the guide-o has lulen adjusted, the stopis moved against the face of the slide 13 and secured there by means of the screw 271' Should the guide 0 suliscquontly be moved away for any ransom it is only necessary on returning it to push it up against the stop to bring; it to the proper position. Should it bs necessary to Wind the arnmture so that the Wire passcs on botli sides of the armature shaft it Will be necessary to replace the Wire holder n by a guide horn similar to the horn m and oxtcnding over the other side of the armature shaft. It is of course obvious that the machine may also be constructed that the cheeks with the armature remain stationary while the Wire supply spool is arranged to rotate about the apparatus,

Having thus described the nature of say said invention and the best means I know of carrying so same into practical effect, I claim :"f" i 1.
